We report PL, PLES, and resonant PL from N isoelectronic traps induced under pressure at 5°K in GaAs. Exciton A and B transitions of isolated N form in the gap above 22 kbar and show strong wavevector-independent phonon cooperation resembling GaP:N. Levels vary with pressure independently of nearby bandedges, thus demonstrating “deep-level behavior.” These bound states derive from a localized resonance 150–180 meV above the Γ1edge.
